Neal,
Multiple LDS applications referencing one TServer is possible. There would, however, be requirements for this. There will need to be LDS + URS pair if multiple LDS are used. So there cannot be 2 LDS and 1 URS (needs to be 2:2). Also each URS must be controlling a unique set of Routing Points as multiple URS applications can't control the same RP.
If we need to dig into this further then may I suggest we open a Case with Genesys Customer Care.
